The Model MMU-1600G Malfunction Management Unit is a full featured that monitors up to 16 traffic signal channels for conflicting inputs, improper sequencing, incorrect timing, and invalid voltage levels.

Setting a new standard for Malfunction Management Units, the MMU-1600G includes an Organic Light Emitting Diode (OLED) display.

• OLED display provides outstanding readability in any light condition and functions reliably over a temperature range of -22º F to +176º F (-30º C to +80º C)
  
  
• NO COMPUTER NEEDED! All logs can be viewed on the OLED graphic display
  
  
• All AC field voltages can be displayed on a single screen, making viewing of leakage voltages on all load switch output a simple task
  
  
• Context sensitive Help system assists configuration and troubleshooting tasks
  
  
• Event Logging provides detailed, time-stamped records of:
  • Time Changes
  • Monitor Resets
  • Configuration Changes
  • Prior Faults
  • AC Line Voltages
  • Signal Sequence Data
    
    
• Configuration Wizard easily configures the monitor for most applications in just a few minutes
  
  
• Optional Ethernet Port - can be added after initial purchase
  • Allows communication with the monitor through a settable Ethernet network IP address.
  • Both the Ethernet Port and the RS-232 Port can be used at the same time


• The most advanced Flashing Yellow Arrow Left Turn monitoring available in the industry
  
  
• Operates in either Type 16 mode (sixteen channels) or Type 12 mode (twelve channels)
